How It Works

Activates three complementary energy pathways: GIPR reduces appetite and modulates lipolysis; GLP-1R delays gastric emptying and increases satiety; GCGR increases hepatic glucose production and brown adipose tissue thermogenesis.

Key Benefits

  • 24% average weight loss (52 lbs / 24 kg)

  • Enhanced HbA1c reduction in diabetics
  • Improved triglycerides and lipid profile
  • Increased resting energy expenditure
